WINDOW MOUNTING.

Application filed June 1.6, 1921.

To all whom it may conceive:

Be it known that I, PHILIP G. PFEIL, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Window Mountings, of which the following is a specification.

This invention relates in general to building constructions, and has more particular reference to the manner of mounting the window sash in the casings.

It is common practice to mount the window sashes so that they will slide vertically in overlapping relation in the casings, and it has also been proposed to pivot the sashes intermediate their sides so that they may be swung about this central pivot, thereby permitting access to both faces of the glass for cleaning purposes.

One of the primary purposes of my present invention is to provide a mounting which will enable the window sashes to partake of the usual sliding movements in the easing and will also permit the sashes, both lower and upper, to swing inwardly. I am therefore, by this construction, enabled to secure in one construction, all of the advantages inherent in both the sliding and pivoted types of mountings.

Another purpose of my invention is to provide a mounting which will permit the counterbalancing of each window sash with a single weight, the mounting being so constructed that the sash counterbalanced at one side only will slide freely and easily in the casing. Obviously, the elimination of one weight, its cord or chain, and the pulley over which the cord or chain travels from each window sash very materially decreases the cost of installation, and the ex-. pense of maintenance.

Still another object of my invention is the provision of novel means for locking the sashes against swinging movements when desired, which means will serve to guide the sashes in their sliding movements and maintain them in proper position in the casing as well as serving as a weather strip for the exclusion of cold, rain, etc.

Still another object of myinvention is to provide a mounting which will be simple in construction, economical to manufacture, easy to install, and one which will not be Serial No. 477,884.

subject to breakage or liable to get out of order, but will be strong, durable, and highly satlsfactory in use.

Other objects and many of the inherent advantages of my invention will be readily appreciated as the same becomes better understood, by reference to the following descrlption when considered in connection with the accompanying drawings.

Referring to the drawings:

Fig. is a face view looking at the inside of a window casing equipped with my invention;

Fig.2 is a fragmentary sectional view on the line 22 of Fig. 1;

Fig. 3 is a transverse sectional view showing both sashes in lowered position;

Fig. 4 is a transverse sectional view with botah sashes lowered and swung inwardly; an

Fig. 5 is a fragmentary view showing the arrangement of the sliding members with reference to the sash cords and pulleys.

From an inspection of the drawings, it will be observed that I have illustrated in the present instance, a window casing comprising the vertical side members 6 and 7, a top -8, and a sill 9, the casing being equipped at one side only with a compartment 11 in which the sash weights 12 and 13 are adapted to travel. Instead of providing the guide strips or stops which are customarily installed in both sides of the easing for the purpose of guiding the sashes in their vertical sliding movement, my invention contemplates the complete elimination of the stops, the inner face of both vertical side members 6 and '7 of the casing being left perfectly plain except for the attachment thereto of the outer stops or weather strips 14: and 15, as shown in Fig. 4:. Both the up per window sash 16 and the lower sash 17, provided with the customary glass panes 18, are formed at one side with the usual grooves 19 for the reception of the window weight cords 21 and the upper end of thecasing member 6 is slotted, as shown in Fig. 5, to accommodate the pulleys 22 over which the sash cords are respectively trained, the outer ends of the cords being attached to the weights 12 and 13 in the usual manner.

In alignment with the upper sash 16, when properly positioned in the casing, I attach to the inner face of the casing member 6 a metal channel-shaped guide member 23 which is secured to the casing member by screws 24, and within this guide member, there is slidably disposed an elongated metal member 25 preferably of substantially the length of the sash 16, this member being equipped near one side and adjacent the top and bottom with hinges 26, one leaf of each of which is secured to the adjacent margin of the window sash 16by a plurality of screws 27, or other fastening means. To accommodate the outer flange of the'guide member 23, the sash is preferably recessed longitudinally, as indicated at 28, thereby permitting the sash to partake of its vertical sliding movements without interference with the guide member. The slide member 25 being slidable longitudinally of the guide member, and the window sash being pivotally mounted on the slide member, it will be manifest that the sash is capable of being raised and lowered within the casing, and is also capable of being swung inwardly relatively to the casing.

Adjacent to the guide member 23 and parallel therewith, I have mounted upon the casing member 6, a similar guide member 23 carrying the slide member 25 to which the lower sash 17 is similarly attached by hinges 26. Both sashes are therefore capable of sliding and swinging movements, and normally, when disposed in closed relation, they assume the position shown in Fig. 1 with the upper edge of the lower sash overlapping the lower edge of the upper sash, as shown in Fig. 2. VVhe-n closed, the upper edge of the upper sash fits behind a ledge or flange 31 depending from the top of the casipg, whereby the top of the sash is held against inward swinging movements. 7

For the purpose of locking the sashes against swinging movement, and at the same time permitting them to partake of the raising and lowering sliding movements, 1 have provided the inner face of the casing on the side opposite from the hinges with a longitudinally extending groove 32 and upon the outer face of the adjacent side of the lower sash, I have mounted a bar or strip of metal 33, which is preferably shaped in cross section, as shown in Fig. 4c, and is provided at spaced intervals throughout its lengthwith L-shaped slots 34; screws 35 extending through these slots and provided with heads larger than the slots movably attach this member to the sash frame. When the member is disposed in the position shown in Fig. 1, its marginal edge 36 projects into the groove 32, thus holding the lower sash and consequently the overlapping upper sash against swinging movement, but permitting longitudinal sliding movements of the sash within the casing. The marginal portion of the member 33 projecting into the groove memes to dispose the horizontal portions of the slots 34. in alignment with the screws 35" whereupon the member is moved laterally to the left, viewing Fig. 1, so as to withlraw its projecting edge 36 from the groove thereby freeing the sash from the casing. This sash may now be swung inwardly from the casing through an angle of 90 intothe position shown in Fig. a so that access to both faces of the glass may be had for purposes of cleaning. Similarly, by sliding the upper sash downwardly so as to free it from the ledge 31, this upper sash may also be swung inwardly, and customarily, when the windows are to be washed, this upper sash is pulled down into convenient position and then swung inwardly into the position shown in Fig. 4. The inward swinging movement of the upper sash is, of course, limited by engagement with the already open lower sash, but a sufficient range of movement for the upper sash is permitted to enable unrestricted access to both faces of the glass. 7

While I have shown wooden sashes in the present instance, it should be obvious that metal sashes may be employed in connection with my invention with equal facility. No special construction of casing is required, and my invention may be applied to old casings already installed, as well as to new, by simply removing the ordinary guide stops and applying my attachments to the casing and window sashes. By reason of the long bearing surfaces between the guide members 25 and the guide-ways in which they slide, such an accurate and easily working guide is provided for the windows, that but one weight is required for each sash. The elimination of the weight at the opposite side of the window not only reduces the cost of installation and maintenance, but also leaves this side of thewmdow sashes free to partake of their swinging movements without being restrained, as they would be by window cords at this side of the casing.

The sashes may be raised and lowered exactly the same as in the ordinary window construction, and they may be swung ining the locking member 33, as previously explained, thus enabling the windows to parwardly whenever desired by simply releasdescription, and while I have shown and described a preferred embodiment, obviously, the invention may be incorporated in constructions differing materially from that illustrated without departing from the spirit of the invention as set forth in the appended claims.

I claim:

1. The combination of a window frame provided with an outer window stop only, the jambs of the frame from said outer stop to the inner edge of the frame being devoid of stops, a pair of upright guideways fixed to one side of said frame, a slide working in each guideway, a pair of sashes slidably disposed in contiguous relation in said frame and hinged at their extreme outer edges to said slides, respectively, the inner sash when in position for normal sliding movement maintaining the outer sash in engagement with said stop, window weights attached to the hinged sides of said sashes and adapted to counterbalance said sashes, the opposite sides of the sashes being devoid of connection to any counterbalance weights and adapted to swing inwardly away from the frame, and adjustable means detachably and slidably connecting the inner sash only with the frame for maintaining said inner sash in position for its normal sliding movements.
